Abstract: To obtain the sustainability of social life and to increase resistance to disaster that cause loss of life and properties; it is possible to raise awareness in the community about disaster preparedness and engross to take all the components. Disaster planning is an approach that targets the correct use of resources to decrease negative impacts in the community after the disaster. In Turkey, earthquake losses have an important role in disaster planning. There are two basic approaches for earthquake loss estimation used in disaster planning namely deterministic and probabilistic. Uncertainties of the seismic risk assessment parameters can be generated from ground motion computations, structural inventories and risk methodologies. In this study, uncertainties in the ground motion estimations are investigated. Gebze district that located close to major fault lines at Marmara region, and had significant damage during Kocaeli earthquake (1990), is selected as a study case for the risk assessment scenarios. The uncertainties parameters in ground motion computation that have major effect on the risk assessment are considered as earthquake source, earthquake magnitude and soil parameters. As a result, building damage ratios, loss of life and the need for shelter are computed. The soil amplification effects on the seismic intensity level and damage ratios are emphasized. The earthquake hazard estimation and risk assessment computation were performed utilizing geographic information system based software AFAD-RED. The software combines the scenario based seismic hazard procedure with the existing building inventories and soil data for the risk estimations. As a result, it is concluded that, uncertainties in ground motion computations have important effect on the seismic risk assessment and should be considered in disaster planning process.

Aims: This study compares the WHO (2007) and the National Health Examination Survey (NHANES III) reference intervals and investigates the differences when applied on a Canadian cohort of older children and adolescents. Methods: We calculated height, weight and BMI z-scores of 4375 consecutive patients (1993 female, 45.6%) aged 5 - 20 years attending outpatient clinics at a single tertiary care centre using reference data of the latest NHANES (III) survey and the WHO (2007) growth charts. To address age dependency, data was stratified into age groups. Results: Using the NHANES III reference intervals, medians of weight (+0.46), height (+0.29) and BMI z-scores (+0.46) were significantly non-zero. The WHO (2007) growth charts yielded medians of +2.05, +0.32, +0.53 for weight, height and BMI z-scores respectively, all significantly non-zero. When comparing both growth charts, Canadian children had significantly different weight and BMI z-scores (p < 0.0001) with WHO growth charts whereas height z-score did not differ. Obesity rates (BMI z-score > 95th percentile) doubled from 8.6% to 16.0%. A significant age dependency was observed with higher WHO (2007) weight z-scores (>7 years) and higher BMI z-scores (7 to 13 years) and no significant difference was observed for height z-scores across all age groups. Gender differences were observed for weight z-scores (>9 years) and BMI (males: 9 - 11 years, p = 0.0118; 11 - 13 years, p = 0.0069) whereas no significant difference was found in height z-scores across all age groups. Conclusion: Our results reveal substantial differences between both reference populations and thus interpretation needs be done with caution, especially when labelling results as abnormal.

Abstract: In the field of analog VLSI design, current conveyors have reasonably established their identity as an important circuit design element. In the literature published during the past few years, numerous application have been reported which are based on a variety of current conveyors. In this paper, an oscillator circuit has been proposed. This oscillator is designed using a single positive type second generation current controlled current conveyor (CCCII+). A CCCII has parasitic input resistance on it’s current input node. This resistance could be exploited to reduce circuit complexities. Thus in this accord, a novel oscillator circuit is proposed which utilizes the parasitic resistance of the CCCII+ along with a few more passive components.

Abstract: Every branch of science has its own special methods teaching within the perspective of its purposes. A teaching method which is appropriate for the structure of mathematics should be according with these stated purposes below (Van de Wella, 1989 );The students; Conceptual knowledge of mathematics Procedural knowledge of mathematics Connections between conceptual and procedural knowledgeThese three purposes are called as connectional knowledge. Conceptual knowledge can be defined as knowledge of mathematical structures (concepts and its elements) and giving them with symbols; and benefiting from its utilities; the knowledge of procedural techniques of mathematics and giving them with symbols; formatting the connections and relations among methods, symbols and concepts. By studying students’ knowledge of mathematics in terms of learning psychology that mentions two kinds of mathematical knowledge. First one is an entirely mechanical data consist of some abilities such as recognizing the symbols, doing the operations ; second one is the ability to put symbols into some mathematical concepts, forming some relationships among them and doing operations by using them (Baki, 1998). While in procedural knowledge, it is necessary to know only how to use knowledge without needing to know the meaning of a concept or an operation; in the conceptual knowledge, the act of conception becomes important (Baki, 1997). Conceptual knowledge and procedural knowledge are two-dependent components. Both conceptual and procedural knowledge are very important in mathematics (Hiebert, and Carpenter, 1992). A permanent and functional learning in mathematics is only possible with balancing conceptual and procedural knowledge (Baki, 1998). It has been more important to have operational knowledge in mathematics, whereas the conceptual knowledge should be predominantly focused on. In other words, the conceptual and operational data are not balanced in teaching mathematics. For the conceptual and operational data are not balanced in teaching mathematics, the subjects are not learned conceptually ( leyen, and I k, 2003). For the lessons are not explained conceptually, the subjects are memorized instead of being learned. Most students are not aware of that there are concepts at the basis of the subjects they learn, and they do not know what mathematics means. They believe that learning mathematics is to operate on meaningless symbols, and they try to learn mathematics by memorizing it (Oaks, 1990). Generally, it is stated that abstract concepts are difficult to articulate, and this

Abstract: “Meta Communication” is the process between message designers when they are talking about the learning process, as distinguished from their articulation of the “substantive” learning, itself. Therefore, it is important to understand how to design reflective online conversations and how to implement a diverse milieu for prospective online learners so that they are able to transfer their information, knowledge, and learning from theoretical forms to real life experiences. This book discusses meta-communication for reflective online conversations to provide digital people with models for distance education. This book brings together meta-communication, distance education, and models as well as reflective online conversations at the same time.The book is consisted of 321 pages covering 17 chapters. Topics covered in this book are divided into four sections: Meta-communicative knowledge building and online communications, dynamic models of meta-communication and reflective conversations, designing online messages for reflections, and meta-communicative assessments and reflective communication skills. The book's broader audience is anyone who is involved in e-learning.

Abstract: Described as “not only the unexistence of a disease or a disorder but also exact wellness in terms of mental, physical andsocial aspects” by WHO, health is term subjectively evaluated by the individual. However, communication described in manydifferent ways so far is the process with its simplest meaning in which information is transmitted from a source to the receiverwith an aim. Health information and communication opportunities are important for the quality of health care applications,succesful of health outcomes and healthier life. Connecting the health and the communication with each other, healthcommunication means “the application of the communicative rules and strategies on procedures performed to develop health.”Health is an area where effective communication is fairly important, as good communication, contributes to improve ofhealthcare quality. Healthcare providers with good communication skills, contribute their success is the achievement of betterhealth outcomes. All informative transmissions related to health on mass media instruments, between individuals, and patientsand doctors are considered in the frame of health communication.Health communication has emerged as a academic field over the past three decades. Health communication goals to improvehealth outcomes by sharing health information. Thus, attempts to change behaviors and to raise of awareness in a target audienceregarding health or health issues and solutions. With this purpose used to health promotion, health education and diseaseprevention methods. In this context “health promotion” is the process of enabling people to increase control over, and toimprove, their health. It moves beyond a focus on individual behaviour towards a wide range of social and environmentalinterventions. “Health education” is training people about health and health issues. An health educational program directed toimprove, maintain, and safeguard the health of the community or person. “Disease Prevention” is focuses on the avoidance ofillness and minimization of threat.Health communication interventions goal is change to health behavior. Health behavior is an action taken by a person tomaintain, attain, or regain health and to prevent illness. A number of theories has been developed to predict, explain, and changehealth behavior. In literature health behavior models that have shaped health communication strategies are drawn primarily fromthe fields of psychology. These theories in this study includes: Health Belief Model, the Theory of Reasoned Action, theTranstheoretical Model, Social Cognitive Theory,

Abstract: In these studies the isotopic inventories and corresponding activities of important nuclides for different fuel cycles of a CANDU reactor have been compared. The calculations have been performed using the computer code WIMSD4. The isotopic inventories and activities have been calculated versus the fuel burn-up for the natural UO2 fuel, 1.2% enriched UO2 fuel and for the 0.45% PuO2-UO2 fuel. It is found that 1.2% enriched uranium fuel has the lowest activity as compared to other two fuel cycles and vice versa for the 0.45% PuO2-UO2 fuel.
